Nokia is reportedly prepping the Lumia 930 and the Lumia 630 / 635, which will be announced during an event on April 19.

The Lumia family will soon gain a new number: the 630. As the name suggests, the Lumia 630 should be the evolution of its mid-range predecessors, the 620 and 625.

The rumors about the Nokia Lumia 630 were strengthened this weekend, when the noble leaker on Twitter @evleaks posted a press render of the phone.

The alleged image shows the Lumia 630 will go on sale in five bright colors: black, white, yellow, orange and green and feature a 4.5-inch display with 854 x 480 pixels resolution without physical buttons.

According to previous reports, the phone is codenamed Moneypenny and will come in two variants: one with a single SIM and the latter with dual-SIM module, running Windows Phone 8.1 on board. The duo will be marketed as the Lumia 630 and 635, respectively, in emerging markets such as India and China.

In addition, the cellular network sign is marked as 3G, and it probably means the duo won’t have 4G LTE connectivity. However, a few reports claim the Lumia 635 will be the combo of 4G and 3G networks.

The duo is expected to be announced at a press event on April 19 by Nokia.

In addition, one of the biggest Windows Phone in a small box heading into the event is the Lumia 930 codenamed Martini. The phone is seemingly the global variant of the Lumia Icon with almost same counterparts in terms of hardware.
